what reason would anyone have
That’s none of your business. You don’t need to know why anyone wants to do a thing to advocate for their freedom to do it.
Just because you lack the imagination to think of reasons someone might have, doesn’t mean that they don’t have a perfectly good reason. But, they shouldn’t need to justify themselves to you.
You don’t know why they might want to do this thing. I also don’t know why they would want to do this thing. The difference is, I 👏 Don’t 👏 Care 👏. My opinion of their reason to want to do it is irrelevant to my advocating their freedom to do it.
And that’s all I’m going to say on the subject. If you can’t understand that basic fact, then I don’t know what else I can say.
